MVO to RO was created by gravedigger
I've spent several hours trying to get rapid override working. I happened to read about the change in the designation from MVO to RO. The Mesa Config program doesn't recognize this yet.
Then I noticed that the manual has the wrong name.
Instead of rapid.rapid-override, it should be rapid-override.
I have now entered the following manually and it finally seems to be working.

# ---max Geschwindigkeit Neufestsetzungs-Signale an Mesa Encoder - mpg (rapid override signals to mesa encoder - mpg)---

net ro-count     <=  [HMOT](CARD0).7i73.0.0.enc3.count

# verbinde max Geschwindigkeit Neufestetzung Inkrement - MPG (connect rapid override increments - MPG)

    setp halui.rapid-override.direct-value false
    setp halui.rapid-override.scale 0.01
    setp halui.rapid-override.count-enable true
net ro-count            =>  halui.rapid-override.counts

I was very close to replacing the Linux CNC with a different system.
The small inaccuracies make it very difficult for a newcomer.

What inaccuracies? In the documentation?

Instead of rapid.rapid-override, it should be rapid-override.

What manual is this in and what LinuxCNC verison?

(the current halui man page does not have this error)

Its really important to read the instructions for the version of LInuxcnc you are using. Often a Google search will display dated info

To connect encoders, the following pins are exported:

gmoccapy.jog.jog-velocity.counts (s32 IN) - Jog velocity

gmoccapy.jog.jog-velocity.count-enable (bit IN) - Must be True, to enable counts

gmoccapy.feed.feed-override.counts (s32 IN) - feed override

gmoccapy.feed.feed-override.count-enable (bit IN) - Must be True, to enable counts

gmoccapy.feed.reset-feed-override (bit IN) - reset the feed override to *0%

gmoccapy.spindle.spindle-override.counts (s32 IN) - spindle override

gmoccapy.spindle.spindle-override.count-enable (bit IN) - Must be True, to enable counts

gmoccapy.spindle.reset-spindle-override (bit IN) - reset the spindle override to *0%

gmoccapy.rapid.rapid-override.counts (s32 IN) - Maximal Velocity of the *chine

gmoccapy.rapid.rapid-override.count-enable (bit IN) - Must be True, to enable counts

Seems you are looking at 'gmoccapy' documentation for using 'halui' pins.

Halui documentation is here:
linuxcnc.org/docs/html/man/man1/halui.1.html#Rapid%20Override

However you should really be using the pins provided by gmoccapy for this purpose.
If unsure comment all lines in your hal files that give errors and use the 'Halshow' tool on the Settings page of Gmoccpy.
Using 2.9.7 I get this (which seems to agree with the documentation for Gmoccapy):
